FORMULATION AND EVALUATION OF PRONIOSOMAL TRANSDERMAL GEL OF DITHRANOL
Patsariya Surendra Kumar*, Middha Anil
Abstract
The current study was undertaken to prepare and evaluate proniosomal
transdermal gel of dithranol. Dithranol (DTH) is a drug which used in
the treatment of psoriasis. Proniosomal transdermal gel has prolonged
delivery and more importance because the proniosomes are more
stable than existing liposomes and niosomes. simultaneously, gel
based formulations are better dermal absorption than other preparation
such as already existing creams and ointment preparation. Therefore,
transdermal gel of dithranol was prepared using different surfactant
and incorporated gel base polymers such as Carbopol 934. The study
encompasses compatibility studies using DSC spectra, drug content,
viscosity, spreadability, and rheological consideration. Optimization of
formulation was subjected to 32 full factorial designs by Design Expert
9.0.1 Version software. Additional, the optimized formulation was evaluated by Rheological
parameter and ex vivo diffusion study. Formulation batch DPNS6F8 was containing Carbopol
934, Span 60 and cholesterol (act as permeation enhancer) showed 89.80 % PDE and drug
Flux 9.89 (μ/cm2/h). Stability studies conducted under accelerated condition were shown
acceptable results. It was concluded that surfactant span 60 produced better results than other
grade of Span with combination of cholesterol. Proniosomes incorporated in Carbopol gel
containing dithranol showed good consistency, spreadability, homogeneity as well as
stability. Proniosomal transdermal gel had wider prospect for treatment of Psoriasis.
